How Can the Guide Wire be Unobstructed?

How Can the Guide Wire be Unobstructed? When fighting against peripheral vascular diseases such as leg artery stenosis or blockage, doctors often use a minimally invasive technique - peripheral vascular intervention therapy. This is like carrying out a delicate "pipeline dredging" or "road repair" inside the blood vessels. In this minimally invasive surgery, a slender and flexible guide wire plays a crucial role as a "navigator". Guidewire: the [...]
